NOW THEREFORE BE IT ORDAINED AS FOLLOWS:
1. That Section 13.815G.(1)a. shall be amended to read as

developments shall be required to assure that (a) all
such proposals are consistent with the need to
minimize flood damage, (b) electrical, heating,
ventilation, plumbing, and air-conditioning equipment
and other service facilities shall be designed and/or
located so as to prevent water from entering or
accumulating within the components during conditions
of flooding, (c) adequate drainage is provided so as
to reduce exposure to flood hazards, and (d) proposals
for development of five (5) acres or fifty (50) lots
whichever is lesser, include within such proposals the
regulatory flood elevation."
2. A new code section 13.815G.(j) shall be added to read
as follows:
"For all new construction and substantial
improvements, fully enclosed areas below the lowest
floor that are subject to flooding shall be designed
to automatically equalize hydrostatic flood forces on
exterior walls by allowing for the entry and exit of
flood waters. Designs for meeting this requirement
must either be certified by a registered professional
engineer or architect or must meet or exceed the
following minimum criteria: a minimum of two openings
having a total net area of not less than one square
inch for every square foot of enclosed area subject to
flooding shall be provided. The bottom of all

in an area other than a basement area, is not
considered a building's lowest floor, provided that
such enclosure is not built so as to render the
structure in violation of the applicable non-elevation
design requirements of this ordinance."
